This project seeks to determine if Solidification and Stabilization (S/S) is a viable remedial strategy for PFAS contaminated sediment. If the process is effective at the sequestration and elimination of contaminant pathways out of the stabilized matrix, then this previously harmful material can be beneficially used as geotechnical fill. Beneficial reuse of contaminated soils on-site can represent a significant cost savings for treatment while providing a value as a product.

The S/S process has not been used previously for PFAS contamination and if successful could open the path for innovative treatment technologies for contaminated soils at aviation facilities. In addition to demonstrating the potential of S/S as a treatment process, during this project, we will determine the binder/admixture type which provides the optimal PFAS sequestration and final material characteristics.
